Roza Robota (1921, Ciechanów – January 5, 1945), referred to in other sources as Rojza, Rozia, or Rosa, was the leader and one of four women hanged in the Auschwitz concentration camp for their role in the Sonderkommando revolt of October 7, 1944.

Born in Ciechanów, Poland, to a middle class family, Rosa had one brother and one sister. She was a member of Hashomer Hatzair Zionist-socialist youth movement, and joined that movement's underground upon the Nazi occupation. Roza often used her Hebrew name, "Shoshanah." She was transported to Auschwitz in 1942, and was sent to Auschwitz-II, the adjacent Birkenau labor camp for women, where she was involved in the underground dissemination of news among the prisoners. No one else among her family in Europe is known to have survived.

Robota worked in the clothing depot at the Birkenau Effektenlager adjacent to Crematorium III of Birkenau, where the bodies of gas chamber victims were burned. She had been recruited by men of the underground whom she knew from her home town, to smuggle "schwartzpulver," a rapidly-burning compound collected by women in the "Weichsel" munitions factory, transferring it to a member of the Sonderkommando named Wróbel, who was also active in the resistance. This schwartzpulver was used to manufacture primitive grenades and possibly to help blow up the crematorium during the Sonderkommando revolt. In her work she was assisted by Hadassa Zlotnicka, another native of Ciechanów, whom Robota apparently enlisted in the resistance. Together with a few other women who worked in the Nazi factory's "pulverraum," they were able to obtain, hide, and turn over to the men of the underground no more than one to three teaspoons of the schwartzpulver compound per day, and not every day. The Sonderkommando blew up Crematorium III on October 6, 1944.
